Discussions that mention bupropion

Depression board

I looked it up on the web and the XL is the longest acting and it says The half-life of hydroxybupropion is approximately 20 (±9) hours, and its AUC at regular state is about 13 times that of bupropion the origional drug.
One other site said 37 hours for the XL..........going with the 20 +/- 9 hours what would be the amount of days it would take the XL to be out of my system.
This is s frusterating as I had NO other side effects from this med but INSOMNIA!! Even off it for 3 today.
